摘要： The camera has a shutter release, a shutter, a device responsive to activation of the release for performing a retarded opening of the shutter, and a device operative when activated for causing the shutter to close. The exposure duration is controlled by an exposure control circuit. When the scene brightness level is within a first range, the automatically selected exposure durations are so short that, during a substantial part of the exposure, the shutter is in the process of changing from its closed to its fully open state. When the scene brightness level is within a second range, the automatically selected exposure durations are so long that, during a substantial part of the exposure, the shutter will already be in its fully open state. The exposure control circuit includes first and second light-sensitive elements, used alternatively for scene brightness levels in the first and second ranges, respectively, and first and second electronic switches connected in the current paths of the respective light-sensitive elements for switching one or the other light-sensitive elements into the exposure control circuit. A master-slave flip-flop has an information-signal input, two mutually complementary outputs and a clock input. The two controllable electronic switches have control inputs connected to respective ones of the flip-flop outputs. A brightness-measuring circuit determines whether the scene brightness level is in the first or the second range, and correspondingly applies to the information-signal input of the flip-flop one or the other of two information signals.

摘要： An infrared measuring beam is emitted from the camera towards the subject, and reflected back as a tiny light spot projected, by an optics which transversely shifts in dependence upon exposure-objective subject-distance setting, onto one, the other or both of two infrared photodiodes. The signals from the two photodiodes are transmitted in processed form to two output flip-flops through the intermediary of a single, shared signal-processing stage, employing time-division-multiplexed transmission of the two photodiode signals, to assure that the signal processing of the two photodiode output signals be as identical as possible.

摘要： A scene-pause counter, a scene-production counter, and a repetition counter are connected in a series. Each counter furnishes its count to an associated comparator which also receives a signal from an addressable read-only memory. Pulse trains are applied to the counters. When a comparator in the series detects coincidence, it initiates counting by the next counter. When the last comparator in the series detects coincidence it can restart the first counter. A program-selector switch causes different address signals to be applied to the memory, resulting in different operations of different durations, in different combinations and sequences. This makes possible projection or exposure of single frames or series of frames with intermediate pauses between the projection or exposure of successive frames or series of frames, as well as repetitions of such combinations of operations.

摘要： A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.

摘要： During the ongoing course of the exposure, the aperture area increases linearly to a maximum value and then stays at the maximum value, the instantaneous amount of exposure light therefore changing correspondingly, even if the ambient-light level remains constant during the exposure. A pulse generator includes a photodetector exposed to ambient light and generates a pulse train of light-dependent repetition frequency, the pulses of which are counted by a light-totalizing counter which eventually generates a terminate-exposure signal. Ideally, the repetition frequency should increase steplessly and linearly, for maximum accuracy, or second best increase stepwise in small steps to approximate to a stepless linear increase, but in order to use an extremely low number of stepwise frequency changes, without loss of system accuracy, no attempt is made to per se keep the light-indicating repetition frequency accurate. Instead, the number and amounts of the repetition-frequency changes are so established that, when the repetition frequency is plotted against elapsed exposure time, it is proportional to a piecewise linearization of the time integral curve of the exposure-aperture surface area, the constituent straight-line segments of the linearization being confined within a predetermined error-of-total-exposure tolerance range. In the case of a linear increase of aperture size concluding in maximum size, this corresponding to a quadratic followed by a straight-line rise of the time integral of the exposure-aperture surface area, the requisite time integral curve, despite its complexity, can, for example, be implemented using as few as only three or even as few as two stepwise changes of repetition frequency, without loss of system accuracy.

摘要： A photographic camera has an exposure objective and a focus adjuster device for changing the subject-distance setting of the exposure objective, as well as a transducer generating actual-setting signals dependent upon the setting of the focus adjuster device. An evaluating circuit, operative for ascertaining camera-to-subject distance on one basis or another, produces digital required-setting signals, expressed using a first encoding scheme, whereas the actual-setting signals generated by the aforementioned transducer are expressed using a different, second encoding scheme. The actual-setting signals are applied to the first input of a comparator stage, whose second input receives a transformed version of the required-setting signals, transformed from the first to the second encoding scheme, i.e., so that the comparator can compare, in a direct and simple way, the actual-setting signals and required-setting signals against each other with both signals expressed in accordance with one and the same encoding scheme. The output signals produced by the comparator control indicator which informs the user of the direction in which the manual focus adjuster of the camera should be moved to improve the camera's state of focus, and/or control the energization of an electric motor or other electromagnetic positioning device operative for controlling the setting of the focus adjusting device.

摘要： A photographic still provided with a magnetizable coating is inserted into a recording/playback device provided with a movably mounted head unit having a set of heads. A rotary motor drives an endless belt in a single direction, the upper and lower runs of the belt always travelling in opposite directions. The head unit is alternately coupled to the upper and to the lower run of the belt, for travel in one and then the opposite direction. Upon each reversal of the travel direction of the head unit, a successive one of the magnetic heads is activated, so as to track a meandering track on the magnetic coating.

摘要： A photographic camera is provided with means for detachably mounting either a flashbulb flash unit or an electronic flash unit. The camera includes a piezoelectric transducer mechanically activatable for generating voltage impulses. When the flashbulb flash unit is mounted on the camera, the voltage impulses are directly applied across the terminals of the flashbulb. There elapses a certain time interval between the start of flashbulb firing and the development of maximum flashbulb output illumination. This time interval is taken into account in the design of the shutter-activating mechanism. When, instead of the flashbulb flash unit, the electronic flash unit is mounted on the camera, the voltage impulses generated for flashbulb firing are utilized to initiate operation of the electronic flash unit. Because the flash tube of the unit develops maximum output illumination more quickly than does a flashbulb, a time-delay circuit is utilized to effect compensation.

摘要： A scanner has a light sensing unit, and a reflecting unit which reflects light to the sensing unit either directly or indirectly. The reflecting unit receives light from an object being scanned or from a light source. In the former case, the light is reflected to the sensing unit directly. In the latter case, the light is reflected to the sensing unit indirectly. Thus, the reflecting unit directs light to an object being scanned and the object transmits or reflects the light to the sensing unit. The reflecting unit is made up of a series of micromirrors, and each of the micromirrors corresponds to a respective point of the object being scanned. The micromirrors are independently movable between rest positions in which they reflect light away from the sensing unit and active positions in which they reflect light towards the sensing unit. The micromirrors are successively moved from the rest positions to the active positions and back to the rest positions so that only one micromirror at a time directs light to the sensing unit. In this manner, scanning is accomplished point-by-point. The scanner can be used in a photographic copier to measure the densities of film frames and thereby regulate the exposure times during copying.
